She's caring, but gets irritated easily, not at Seventeen though, Three's always calm around them
Three (3) is an Algebralien. Three is the main catalyst behind how the majority of the Algebraliens got their powers from the Yoylite, including the abilities of Four, X, and Two. After her value was broken when One tried to recover her, Four took her to the EXIT to keep her safe. After the Algebraliens' departure from their home planet, Four made several attempts to properly recover her and restore her value, to no avail.
